Founded in 1957, RMI began as a manufacturer of traditional optical components. Today, RMI has evolved into a world class operation that includes the design and manufacturing of full spectrum (Deep Ultraviolet through Far Infrared) optics, thin film coatings, optical assemblies, and opto-mechanical components for laser and imaging applications.

Since purchasing the company in 1983, Dr. Yubong Hahn, a recognized expert in high power thin film coatings, has transformed the RMI Optical Division from a seven person optical shop into an established player in the photonics industry and a leader in the production of the highest quality precision optics.

RMI has established a high degree of experience working with several major industries, including Medical, Defense, Semiconductor, Industrial/OEM, and Research and Development. Our custom capabilities and new material production facility allow us to make some the highest quality optical products for companies all over the globe.

The cornerstone of the RMI service philosophy is a collaborative approach with our customers to solve even the most technically challenging requirements. Working with clients in the early stages of development, we transition prototype concepts to efficient and manufacturable solutions.
